I ICE FOR ADJACENT-PARTS OF MACHINER E. LEIITZ, JR, ET AL ADJUSTING DEVFiled Nov. 21. I939 JNVENTOR Y mmy flwa/r V TOPN head of the securingscrew. when in the form of an outer gearing on the sleeve engageable bythe separate key l2.- It is therefore possible to observe parts from theside as distinguished from spacing means which are operable axially ofthe device. advantage is that there are no parts projecting above theuppersurface of the part the latter is screwed home within the sleevein' Fig. 1 orinto the threads I8 in Fig. 3 the two held together inexact spaced relation and. the holding sleeve firmly pressed intoengagement with the surrounding wall of the part I.

object. of the invention that the means may be key bore at any angle tothe axis of the sleeve as shown in Fig. 3. This arrangement allows theground of the threaded bore venting engagement between the and the outergearing on the sleeve We claim:

5 without pretoothed key l2 1 or 20.

juxtaposed relation comprising a sleeve, screwed into one of the formedto engage the inner a screw extending through the other part and havingthreaded engagement with the interior of the sleeve to secure the twoparts together, and means for moving the sleeve and screw axially toadjust the position of the sleeve, including gearing onthe sleeve and akey engageable with the gearing to move the sleeve and thereby adjustthe distance between the confronting faces of the two parts. v

2. A device for securing two parts together in juxtaposed relation,comprising a screw extendexcept the I ing through one of the parts. asleeve-like part threaded into engagement the other part. one of the twolast-named parts having said sleevewith the '5 and means for moving thesleeve-like part and screw a to adjust the position of the sleeve-likepart whereby to adjust the space between th fronting faces of the twoparts to be secured together, said means including gearing on the sleeveand a key engaging the gearing to move the sleeve to adjust the spacebetween two parts to be secured together.

3. A device for securing two parts in accord- 15 ance with claim 2,wherein the key has means on its end engaging the gearing of the sleevewhereby to rotate the latter.

4. A device for securing two parts in accordance with claim 2, whereinthe gearing is formed on the exterior screw threads of ance with claim2, wherein the gearing is formed on the threads; and on its inner endengaging the gearing.

6. A device for securing two parts, in accordance with claim 2, whereinthe sleeve-like part is axially split and has a tapering bore;whereinthe screw has a similar tapered portion engaging the tapered boreof the sleeve-like part whereby upon rotation of the screw to expand thesleevelike part, and wherein the threads which engage the threads of thescrew, are formed in the said other of the parts'to be connected.
